This gives; Elements Attributes Ordered? schema dependent Probably not Unique? schema dependent Yes structured? schema dependent No Which still shows that anything attributes can do elements can do too - but not vice versa. Henry's suggestion used a leading "." to flag an element to be interpreted as an attribute but this leads straight to the question of why use real attributes at all when the schema can be designed to do whatever you want with elements? If a particular schema language prevents you from doing all these things with elements then because the three basic constraints are orthogonal, there will always be problems. I think Henry's post illustrated one such problem coming to the surface.
